Shynocell will be a one-stop shop where customers can buy mobile credit (pulsa), data packages, and top-up popular mobile games such as Mobile Legends. The flow I have in mind is simple: a visitor selects the product, pays via the built-in QRIS gateway—or, if they prefer, through Bank Transfer or an e-wallet—and the order is sent instantly to the Metro Reload API for fulfillment. As soon as Metro Reload confirms success, the system should mark the order complete and email/SMS the customer automatically. Key elements to build: • API layer that authenticates, sends, and tracks transactions with Metro Reload. • Payment module supporting QRIS first, then Bank Transfer and common Indonesian e-wallets. • Admin dashboard where I can add or disable products, adjust prices and profit margins, and view real-time sales reports. • Modern, responsive UI so the same codebase works flawlessly on mobile and desktop. • Error handling, auditing logs, and basic security best practices (rate limiting, CSRF, etc.). Deliverables for hand-off: 1. Fully functional, production-ready website deployed to my hosting (or a clear deployment script if you prefer). 2. Complete, well-commented source code. 3. A concise setup & installation guide covering environment variables, database migrations, and how to swap Metro Reload credentials should I ever need to. I’ll test by purchasing a sample pulsa, data package, and Mobile Legends diamonds; payment must clear and credit must arrive without manual intervention. Once it does, we’re done!
